I think that improving your communication with him would be an even
better idea than buying some kind of 'scientific calculator' the nature
of which you don't even know what he wants or needs.
More likely there is another different kind disconnect between what he
might use for homework for a chemistry class vs what he might use for
advanced placement testing than this other kind of disconnect we are
seeing here.

stopped buying battery packs for it after the first couple and just
use the ac adapter. It was 400 bucks when they first came out. I think
I paid about 200 for mine. Soon after that Texas Instruments came out
with one for like 20 buck or so. Not sure about the figures but it was
back around 76 or so plus or take a year or two.

My HP41CV is a bit past it now, but the HP48GX is going great. I just
love the big screen and the symbolic integration , graph interrogation
it does, all the electronic and mechanical equation solving. It must be
about 16 years old, I wonder what the new models are like.
Only problem was it was difficult to use in any kind of exam it's so
jammed pack with features, then the el cheapo calculator was used.

Many/Most tests are designed so that calculator usage would be
'inappropriate' -- so as to not give one person with better calculator
muscle an advantage over another. The actual calculations are taken out
of the testing process and calculators aren't to be used. The multiple
choice answer would more likely be in the form of an equation or
mathematical or scientific expression or formula.

Difficult as in banned, not to use the features.
Sorry about that.
I dumped AOS calculators while still at school, once I tried my first
RPN calculator.
It was great for calculating semiconductor yields, using the stack ,
common to all of those type of calculators.
Part of the ban was because -
You could solve equations of a line move the cursor on screen and get
back the numbers the question was for. It was even better for volumes of
revolulution and calculating the volume between cordinates simply by
marking points on the graph.
Or OTOH enter an equation symbolically , and rearrange to find the
required term.
Not forgetting the 2D and 3D graphs and a few 1000 functions.

tell you a war story <g>), the only thing you could take into an exam, was
your brain. I didn`t use
a calculator in an exam, `till `85 when I sat my City & Guilds Comp. Tech.
Oh to be young again.
